"I had the pleasure of working with Dave for my kitchen renovation. From start to finish, their attention to detail and craftsmanship were truly remarkable. The contractor displayed excellent communication skills, always keeping me informed about the progress and any changes that needed to be made. Not only did they complete the project on time, but they also exceeded my expectations in terms of quality. Every aspect of the kitchen, from the countertops to the cabinetry, was flawlessly executed. Additionally, Dave was highly professional and respectful throughout the entire process. They were always punctual and ensured that the work area was clean and organized at the end of each day. It was a pleasure having them in my home."

"Anthony and his crew were friendly and professional throughout the whole project. Anthony gave us a clearly broken down estimate prior to starting the work and we were very confident in his work from start to finish. He and his crew did an excellent job and we would absolutely use him again for future projects. His prices were reasonable and comparable to other quotes we received-he provided us with a clear payment schedule over the course of the project, communicated with us every step of the way and went above and beyond to give us tips and additional info that was helpful to us as new-ish homeowners. Would absolutely recommend."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Robert did a wonderful job of bringing the best architectural solution for our 2nd-floor addition project. He is very detailed and very knowledgeable person. He is very friendly and dedicated to work, but I was not able to move forward with the project due to budgeting concerns. Now the project has been postponed. I will work with him when I resume this project. Great job!"

"Mr. Powers, at first, was courteous and reliable; the project seemed to have problems, and he was getting frustrated at having to surface the existing deck due to its configuration; he claimed that the measurements and figures were off, while another professional disagreed with his calculations; the project was delayed due to materials being delayed by supplier; Mr. Powers suggested another other remedies for steps and that I purchase an additional type of board for $120, which I did; i paid Mr. Powers in full of the understanding that he would come back and finish off certain areas; during this time, a death occurred and he was unable to come when scheduled; when I texted Mr. Powers, he began belligerent, and cursed at me. I do not find it professional to curse at a client and refuse to take phone calls. I ultimately told Mr. Powers not to come back to my house and to refund the board I purchased that was in his possession. He did so. Since the time of completion, May 2026, numerous boards have come loose. I had someone else correct this issue, and now more boards are coming loose, which I texted him about and showed pictures of on September 9, 2026, and have not heard back from Mr. Powers regarding acknowledgment or addressing the loose boards, as my contract provides for two (2) years."

"I cannot speak highly enough of the exceptional craftsmanship and professionalism displayed by Mr. Casteñeda and the employees ofJMC service corps. Their attention to detail and precision in installing the porch railing was truly impressive. Not only did they deliver outstanding results, but they also demonstrated a deep understanding of design aesthetics, seamlessly blending the railing with the overall architecture of the porch. It is evident that they take great pride in their work, and their commitment to excellence is truly commendable. I wholeheartedly recommend their services to anyone seeking top-tier contracting work."

FAQs for addition to existing structure building service projects in Massapequa Park, NY

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
